Frequently Asked Questions

Are your teams fully in-house?

Yes, we don’t work with any external contractors, except when they are brought into team by the client.

Do you offer end-to-end product development services?

Yes, we do. We can handle each phase of product development, from start to finish, or just the parts that you require. We take pride in our ability to build your Minimum Viable Product (MVP) from scratch and assist in scaling it up afterward. Whatever your needs, we are here to help bring your ideas to life.

Are your engineers fully dedicated to one project?

Yes, we avoid giving our people multiple projects at the same time because it dilutes focus. This said, some projects that are in the maintenance phase or require less than 3h of work per day can share resources.

What industries does JSGuru specialize in?

We build software for many different industry verticals, mainly for:

  • fintech
  • real-estate tech
  • edtech
  • marketing and ad tech
  • media and telecommunication
  • ecommerce
Can we add just a couple of your engineers to our existing teams?

Yes, that is possible. It is really important that we set up good working procedures in the beginning and find engineers that are a good fit, technically and culturally speaking.

How long does it take to begin a project with JSGuru?

The duration of the project kick-off process depends on the project’s complexity and the client’s existing resources. If the project requires ideation and market research from scratch, the process may take longer compared to when the designs are already prepared. Typically, the range for the project kick-off is 2 to 4 weeks, but several factors influence this timeline. We will work with you closely to determine the best timeline for your project.
